Reset Samsung S6 (+ variants) + battery tips

February 4, 2016 Leave a comment

It is simple to reset the Samsung S6. Sometimes this is necessary to improve battery life
and performance or just remove clutter from your phone.

First us Samsung’s excellent Smart Switch software (d/l from Samsung for Windows or OSX) and
backup your phone. The software backs up all your data including sms, email settings, etc.
It is very quick also.

Then do a hard reset by holding volume up key, home key, and power key with the phone
powered off. release the home key as soon as you see the Samsung logo and you should boot
into the recovery mode.

Then select from Recovery Mode menu “wipe data / factory reset” using Volume buttons to
navigate and Power button to confirm. After restarting your phone, connect backup to
your desktop and restore your phone with Smart Switch.

You find a few apps with setup requirements but it’s mostly painless.

After months of ownership and many experiments, I have found the best setup for battery life
on my S6-active was to change wifi-settings to enable wifi only while awake (#1 battery eater if
you enable wifi while sleeping) or if you don’t need/care about data usage, leave wifi off.
Also use android email app and only sync during most important part of day (settings has ability
to sync during specified hours) for your email. You can manually sync at other times.

If you take this approach, your S6 (or at least my S6-Active) shows 50+ hours standby after a full charge.

You can easily clone like routerboard hardware with these commands:

First to ssh admin@youripaddress or run terminal from winbox and run the following on the device you want to clone in this example we clone an rb751g to rb951.

## on rb751g type:
/export compact file=name

Then copy the name.rsc file to the rb951 $$either drag and drop it to files with winbox or use sftp.

hard reset the device you want to clone to by powering off and holding reset button, powering on,
and releasing reset button when led next to power plug starts to rapidly flash. Wait until the
os initializes and access with winbox.

## on rb951 type (after hard reset):
/import name.rsc ## you should see no errors.

## then on rb951 type:
/system reset run-after-reset=”name.rsc”
This will clear the current config and import the one from the rb751g

After a minute to load or so you should be able to access the rb951 with winbox and have a complete clone
of the rb751g.
